To all whom it may concem:

Be it known that I, WINFIELD S. RODEN- Bnnenn, a citizen'of the United States of America, residing at Linton, inthe county of Greene and State of Indiana, have invented` new and useful Improvements in `Graphophone Attachments, of which the following is a specifica-tion.; y .Y f

This invention relates Vto graphophone attachments; and one of the "principal objects of the same is'. to -provide simple, reliable and eliicient, means for feeding needles to the soundbox. g Another object of the invention is to proe a magazinepcontaining needles and to provide means whereby said needles may be quickly inserted in the stylus holderf, of the sound box, and at the same time drive out In the use of graphophones it becomes necessary to insert a new needle after one or ,two reproductiens, and these needlesl being small, itis quite diiiicult to feed them in place properly by hand.

My invention has for its object to provide means for quickly removing the old needle and inserting a new one in its place.

These and other objects may Vbe attained by means of the construction illustrated in the accompanying drawing, in which:

` Figure 1 is a front elevation of a graphophone sound box or reproducer having my attachment connected thereto. Fig. 2 is a perspective view Vof the supporting bracket for the' needle magazine. Fig. 3 is a side elevation of my attachment. Fig. 4s is a vertical section on the line 4% of Fig. 1. Fig.

5 .is a sectional view of the stylus holder.

Fig; 6 .is a detail rear side elevationof the magazine and the plunger.

'Referring to the drawing for a more particular description of my invention, the numeral 1 designates the sound box or repro-y ducer of a graphophone of ordinary construction, and 2 is a bracket secured to the sound boxby meausof screwspassed through the openings 2:3 in said bracket. Supporting arms 4 extend outward andupward from said bracket 2. It will be understood, of course, that other means maybe utilized for supporting the magazineupon the sound box or reproducer, depending upon the shape andmanner of attachment of said reproducer.

The magazine 5 may consistof a front plate 6, a sliding back plate 7 and spacing .ed at one end to a ing downwardly The springs 23 pushed dowi Ward which its place,

strips 8 through which suitable fasteners 9 are passed to hold the parts in relative position. Suitable loops 10 are provided upon the back of the maga-zine inv proper position to receive the arms 4 on the bracket 2 to support the magazine in proper position. A plunger support 11 is connected to the magazine anda plunger rod 12 passes through a y.hole'in said support and is provided with an encircling spring 13 which holds the plmgr up in the position shown in Fig. 6.

. e P head or button 14. The end of the plunger extends through an opening 15 in the upper edge of the magazine in line with the feed openings 16 at the lower edge of the magazine. A series of needles 17 are placed in the "magazine and are fed toward the feed opening 16 by means of a spring 18 connectstud 19 While the opposite end is connected to a block 20 fitted to slide in the magazine. Connected to. the block 20 is a knob 21 by means of which the block 20 may be mpved backward whenever it is required to refill the magazine.

The stylus or needle holder 22 is provided with a detent consisting' o f a spring 23 and a pin 24 having a beveled end y25 which will permit the plunger 12 to move past it or the needle 17 to be driven through the opening 26 to drive out the needle 17a. The pin 24 prevents the upward movement of the needle 17l and said needle is prevented from movby means of aspring 27 provided with a stud 28 which passes through an opening 29 in the needle holder and bears with suiiicient friction against the needle to prevent it from dropping out. and 27 are held in place by a pin 30. Y

The operation of my invention may be briefly descrined as follows: l/Vhenever it is desired to force out the old needle and to replace it. by a new one, the plunger 12 is pushes one of the needles 17 .ti'irough the opening 26 against the needle 17al to push the same out' of the needle holder, while the new needle 17takes and is held in'the same position aswas the needle 17 1. After each. needle has been inserted the sprin' .18 moves the sliding .block 20 and :the co umn of needles into position so that one needle a position immediately above the feed opening 16, as Will be understood.-

-From the foregoing it will be obvious that.

unger 12 is provided with a suitable y always occupies struction; can be attache to any form of reproducer Without material change in the form of bracket; that the needles can be fed y instantly Without requiring exact fitting as tachinent, as a whole,

would be the case by' hand, and that the atcan be produced at slight cost. f

Having thus described the invention, what I claim' is:

The combination of a `raphophone reproducer provided with a racket having up- Wardly' extending supportingarms, a magazine for stylus needles provided With loops or eyes upon its rear surface to engage said arms, a guideway in said magazine to support a column of needles, a block itted to l slide inthe guideaa 'springlc'onnected `to said block at one. end and to a stud on the magazine at the opposite end, a plunger Ifor forcing one needle at a time 4out of the magazine into the vneedle `holder of the re,.-kr producer, a sprin' detent havin a beveledy end disposed within the throat o theneedle holder, and a spring having an inwardly projecting stud to bear against the needleto prevent it droppingk out by the plunger.

In testimony whereof, I alix in presence of two Witnesses.
